MACHINE FOR OPERATING UPON SHOES,

Application led March 13, 1916.

To all whom t may concern.'

Be it known that I, EDWARD H. BAs'rAnLn, United States, residing at South Braintree, in the county of Norfolk and. Statev of Massachusetts, have invented certain wnevv and useful Improvements in Machines for Operating Upon Shoes; and I do hereby declare thefollovving to be a full, clear', and eXact description of the invention, such as will enable others skilled in the art to 4 which it appertains to make and use the same.

This invention relates to machines for operating upon shoes, and more particularly to a machine for operating upon the outsole attaching flange of'a lasted shoe.

`In the manufacture of Welt shoes, stitched down-shoes and some types of McKay shoes,

theloutsole is attached to a flange Which eX- .tends outwardly from the shoe upper. The

outwardly extending flange may be the'yvelt or its equivalent, or a portion of the upper, or the edge of' a sole attached to the bottoln of the shoe. In many types of shoes the outseam is embedded in the face of the attaching flange, and if the flange is in proper temper the seam can be more readily embedded therein. If thc flange is not in proper temper it is necessary to cut a channel or groove in the surface of the flange, in order to embed the seam, and this often' results in such.

a deep cut that the outseam will break through the flange.

The primary object. of the present invention is to provide a machine for moistening the outsole attaching flange of a lasted shoe so that itwill be in proper condition for the outsole stitching. operation.

In accordance with this object, one feature of thein-vention contemplates the provision in a machine for operating upon shoes having means for supporting a shoe, of a moistening device for moistening the outsole attaching flange of a lasted shoe, comprising a mechanism movable into and out of contact with said flange, and means for supply ing liquid to said means.

-'lthe preferred form of the invention em-l ploys a moistening device Which is embodied in a rough rounding and channeling machine. The moisture applying mechanism is attached to the forepart guide, and arranged to be moved into or out of contact with the Welt or outsole attaching flange When the forepart guide is moved into and out ofcon- Specification of Letters Patent.

tact with the shoeuppcr. Moisture is supplied ,to the applying mechanism from a tank which has a valve operated by the movement of the forepart guide so that the moistening liquid will only be admitted to the mechanism when it is in contact with the welt.

The welt or outsole attaching flange should be moistened before the outseam stitching operation. If thel welt has been previously moistened .for the inseam sewing operation itoften becou'ies dry and hard 4before it comes to the outseam sewing operation. Also. in many cases, the welt has never been moistcned, so that the operator of the outseam sewing machine usually moistens the welt by hand with a brush before sewing the outsole. This operation is objectionable because it often acts to strain the uppers, and the welt is not thoroughly inoistened and has no opporti'mity to temper. By applying the rough rounding and channeling machine, the moisture has ample opportunity to ternper the welt before the outseaming operation. and the extra hand moistening operation is notnecessary.

Another object of thc .invention is to provide a moistening device by which the liquid for moistening the outsole attaching flange may be accurately controlled.`

.'In accordance with this object, another the invention contemplates the provision in a machine for operating upon shoes having means for supportingand guiding a shoe, of a device for moistening welt moistening device to the' the Voutsole attaching flange of a shoe, comprising a flexible liquid applying mechanismA vforrubbing only the surface of sa1d flange,

and means for supplying liquid to said mechanism. rlhe preferred form of liquid applying mechanism consists of a brush which is arranged to rub over the face of the Welt. Shields are employed to confine the bristles of the brush to the face of the Welt and to hold the brush out of contact with the upper. The moistening liquid is conducted through the center of the vbrush to the bristles, and the bristles work themselves into the face of the Welt and insure that the liquid will be applied to the desired portion of the Welt.

Other features of the invention consist in certain features of construction and combinations of parts which are hereinafter delli. ln this way shoe and -liouid applying scribed and pointed out in the appended claims.

The various features et the invention are illustrated in the accompanying drawings, in which Fio'ure l is a view in side elevation snowing suoli parts of a rough rounding and channeling machine as are necessary to illustrate the application et the improved moistening device thereto; Fig, 2 is a view in front elevation oft-he parts shown in Fie.' l; and Fig. 3 is` a detail sectional View oli the irush.

in the drawings the invention is shown as embodied in a rough rounding and channeling machine having` the construction fully shown and described in the patent to lerry, No. 1,030,606, granted dune 25, 1912K This machine is provided with a work support 10, a rounding knife l2, a channel knife le, a crease guide 16, and a torepart guide 18. The torepart guide is mounted on an arm Q0 which swings about an axis :22 and is connected by means of a 'link 24e and levers 26 and 28 with a rod 30 which is secured to a foot treadle. The above mentioned parts are fully described and illustrated in the atent above referred to.

1 rEhe welt is moistened during the. rough rounding and channeling operation by a brush which contacts the welt immediately behind the orepart guide 18. The liquid applying brush consists of a hollow stem 52 to which is attached a set oi: bristles 3l,

shield is placed around the bristles, and has a guard 3S on thel side adjacent the shoe upper which will contact the upper and hold the brush away from the upper. guard 40 opposite the guard 38 serves to confine .the bristles of Welt. The stem 32 is mounted in a ln'uclret l2 which is attached to the 'iront end of the arm Q0. llilith this construction the brush will move with the orepart (guide, and when the guide brought into contact with the upper, the brush will be applied to the welt. Vlhe stein 3Q is adjustable in the bracket 42 relatively to the shoe support lO, and is held in adjusted position by ,mea-ns of a set screw the bristles can be adjusted kto press againjstrthe tace of the welt sothat #they will worlr themselves into the uneven face ot the welt. v

rFine hollow stem 32 of the brush is connected by a flexible tube 46 with a valve 48 which forms the outlet of asupply tanlr 50 for holding the moistening liquid. This liquid is usuallyA water, but may be any term of solution tor properly tempering; the welt, rllhe liquid iiows down 'through the hollow stem 32 and comes in contact with the bris tles which serve to conduct the liquid to the face of the welt.

rlhe moistening4 liquid is admitted to the brush only when it is in operation upon the is tcmatically shut of when ine the brush. to the tace of the integer brush is not in contact with the welt. To accomplish this result a lever 52 formed on the valve is connected by means ot an adjustable link 5l with a swivel 5G which is mounted in the torepart guide arm 20. The torepart guide is used in guiding the shoe when operating` about the torepart ot the shoe, and is brought into contact with the shoe by the toot treadle. When the guide is brought down into contact with the upper, the valve i8 is set in the position illustrated, in Fig. 2, and when the guide is withdrawn from the upper, the valve will be closed. The extent of opening ot the valve, to control the amount oi water admitted 'lo the brush may be 'varied by an zuljustincut ot the link 54. 'ln this way the dill'erent. types ot weiting may receive the required amount ot liquid to properly temper them.

Thilo the invention has been illustrated as applito a rough rounding and chau-- neling und ine, its application is not lim ited to such use, but the ternpegiim` device may be used with any machine which operi ates upon lasted shoe after the welt has been beaten out.

Having thus described my' invention, what is claimed as new iszl.
